Do you have any tips for my flight to Riverside?
No matter where you're coming from, flying can be a seamless experience if you've prepared well. Take a peek at these essential travel tips that will help get your Riverside escape started on the right foot. What to pack in your hand luggage:

  • The secret to having a hassle-free flight experience is to pack ahead. So, let's start with the essentials: passport, official ID, bank cards and vital medications. Next, bring items that'll help pass the time, like your laptop or a good book. It's also wise to bring your chargers, a neck pillow and a pair of noise-canceling headphones. Last but not least, be sure to pop in toiletry items like a toothbrush, cleansing wipes and a spare set of clothes.

Do not pack the following items in your hand luggage:

  • Check carefully that you don't have sharp objects (like a knife or scissors) hiding in one of the compartments of your hand luggage. Other banned items include flammable or explosive products, such as aerosol cans and bleach, and liquids and gels in containers larger than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • You'll want to choose comfort over style. Prepare for changes in cabin temperature by layering up, and opt for flat, slightly roomy shoes like slip-ons.
  • You've probably heard about deep vein thrombosis (DVT), a blood clot condition caused by long periods of inactivity. To lessen your risk on board, stay hydrated, consider wearing compression socks or tights and do gentle foot and leg exercises in your seat.

How to get through airport security fast when flying to Riverside?
The simple answer is — be prepared. We've compiled some useful tips for a speedy trip through airport security. Watch out Riverside, here you come:

  • Keep your ID and boarding pass someplace easily accessible. They're the first things you'll be asked to present to airport security.
  • The X-ray machine is up next. Empty your pockets and remove anything metal that is likely to beep. This includes items like headphones or earphones, as well as bulky coats or jackets. They'll all need to go on the X-ray conveyor belt.
  • For just a few minutes, you'll need to unplug from technology. Your phone, laptop and any other electronic gadgets will need to go through the scanner.
  • Remove gels and liquids from your carry-on luggage. They usually need to be sent through the X-ray machine separately. Each product should be in a container no larger than 3.4 ounces (100 milliliters) and everything must fit inside a quart-size (one liter), clear zip-lock bag.
  • The right choice of footwear can save you valuable minutes. Hiking boots are often required to be removed and X-rayed separately. Slip-on sneakers are usually not.
  • Airlines will not allow any sharp or pointed objects in the cabin. If you need to bring these kinds of items, check them in.
